New IEC 61000-6-7 released – EMC Immunity in Industrial Locations

The IEC 61000 series covers the essential requirements for controlling EMC.  Now the set has been expanded with the addition of IEC 61000-6-7, “Electromagnetic compatibility (EMC) – Part 6-7: Generic standards – Immunity requirements for equipment intended to perform functions in a safety-related system (functional safety) in industrial locations.”  The document was developed to help you when there’s no relevant information on the electromagnetic influences for functional safety.  Because it is used when there’s no specific information on your situation, it’s considered a generic standard.

Who’s going to be using IEC 61000-6-7?  Suppliers should confirm their products meet these requirements when making claims for the immunity of safety-related equipment against electromagnetic disturbances.  And their customers and assessors should also be using it to confirm that such equipment meets these claims as well.

What locations has it been developed for?  It’s for industrial locations that usually have a separate power network dedicated specifically to them.  These might include facilities that do metalworking, car production, working with pulp and paper, or are chemical plants.

What topics are covered by IEC 61000-6-7?  After the usual scope, referenced documents, and definitions sections, the standard provides you with a general overview of the subject.  It discusses conformance to IEC Guide 107 and IEC/TS 61000-1-2.  It covers performance criteria and your test plan. And immunity requirements, test setup and philosophy, and the test results and report are also addressed.  Annex A provides you with a strategy for functions intended for safety applications.  And the standard is completed by the 14-item bibliography.

Since there’s a relationship between electromagnetic disturbances and systematic failures, you’ll want to insure that you’re providing your facility with the best practices available.  So you’ll want to get a copy of this new standard.  Go ahead and order your copy at the Document Center Inc. webstore at www.document-center.com.  Or contact our staff for more information by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).
